Before launching an instance, you need to configure a security group. A security group is a set of IP filter rules that defines networking access and makes it possible to grant SSH access to users or be able to ping an instance. By modifying the default group or creating a new one you can attach a security group to (specific) instance(s). Key pairs are SSH credentials that are deployed into an instance when it's first deployed.
